Geography
Country:Greenland
Coordinates: 74.1° North, 23.0° West (view map)
Paleocoordinates:30.8° South, 48.9° West
Basis of coordinate:estimated from map
Geographic resolution:outcrop
Time
Period:Cambrian Epoch:Early/Lower Cambrian
10 m.y. bin:Cambrian 2
Key time interval:Dyeran
Age range of interval:516.00000 - 513.00000 m.y. ago
Stratigraphy
Formation:Ella Island
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Ella Island Fm, which overlies the Bastion Fm and in turn the Kløftelv Fm (lower Cambrian) and is overlain by the Hyolithus Creek Fm (lower-middle Cambrian) and Dolomite Point Fm (middle Cambrian). STRATIGRAPHIC POSITION: From the basal part of the Ella Island Fm (see fig. 1), immediately above GGU 314814. AGE: Well constrained to the late Early Cambrian (Dyeran Age or Bonnia-Olenellus Chron; see Palmer 1998) by the presence of Olenellid trilobites (Poulson 1932, Cowie and Adams 1957) and baltisphaerid acritarchs (Vidal 1979). THICKNESS: Thickness of strata collection is derived from must be less than 30 m, and lies within a 80-100 m thick section.
Lithology and environment
Primary lithology: lithified "limestone"
Secondary lithology: calcareous sandstone
Includes fossils?Y
Includes fossils?Y
Lithology description: GENERAL LITHOLOGY: Limestone, in places oolitic. LITHOLOGY: Lithified, based on figured specimens and facies description.
Environment:shallow subtidal indet.
Geology comments: ENVIRONMENT: High energy, shallow-water environment.
Taphonomy
Modes of preservation:body,cast,mold/impression,original calcite,original phosphate,replaced with phosphate
Size of fossils:macrofossils
Fragmentation:frequent
Spatial resolution:parautochthonous
Collection methods and comments
Collection methods:bulk,chemical,acetic,sieve,field collection,survey of museum collection
Reason for describing collection:taxonomic analysis
Collection method comments: COLLECTOR: Collected by S. Peel and M.P. Smith (1988), and earlier collectors. PREPARATION: Rock samples were dissolve in buffered 10 percent acetic acid to retrieve acid-resistent microfossils. The resulting residues were sieved and the heavy mineral fraction separated using sodium polytungstate. REPOSITORY: All specimens are housed in the Geological Museum in Copenhagen (MGUH).
Taxonomic list comments:COVERAGE: Exhaustive for Brachiopoda. The residues of the acid-digested samples contain a well-preserved and diverse small shelly fauna including helcionellid molluscs, coelosclerites, lapworthellids, and problematic fossils. NOMENCLATURE: Authoritative publication, with occurrences identified to species resolution where possible and with modern nomenclature.
